I've started an Amazon affiliate site and I'm trying to rank in the top 5 for a number of long tail keywords. My keyword research has shown that there is very little competition for most of them. Just finalised the site a day or two ago and got the first 5 articles up there - 4 of them are ranking from #29 to #78 for my chosen keywords and one doesn't seem to be ranking in any notable position. This is my first online venture and I'm still getting to grips with IM - would anyone be able to point me towards the best free / low budget link building methods I need to be employing to get these sites to the top within the next few months? I feel that a lot of the stuff I'm reading is going over my head and doesn't actually pertain to me, so I'd just be really grateful if someone could just give me a little push in the right direction.
